“…This study is an attempt to obtain a set of generic reference values to be used in future measurement campaigns of compatibility between DVB-T broadcasts in the UHF bands, and a wide range of personal mobile services, under the generic characterization of IMT-Advanced (successor of IMT-2000) by ITU [17]. This measurement campaign utilized a generic unsuppressed w-cdma base signal as the source of interference, though a number of other signals can be utilized to simulate specific conditions of DVB-T and other services coexisting and sharing the "digital dividend" [18,19].…”

With the advent of DVB-T in most European countries, the European Union has decided to end all analogue television broadcasts in its member countries until 2012. This analogue switchoff, as well as the increased spectral efficiency of the DVB-T protocol will create a surplus of spectrum in the UHF band, part of which is to be used by mobile communications systems. In order for this "digital dividend" to be shared efficiently, the coexistence and interference parameters between DVB-T and other services (designated as IMT-Advanced by the International Telecommunications Union) have to be studied. In this paper a generic 5 MHz interfering signal is broadcasted in close proximity to a stationary DVB-T receiver. Various DVB-T parameters are then measured and analyzed for different frequency values and power levels of the interfering signal.

“…According to the standard specifications in , the IEEE 802.22 is intended to employ wireless regional area networks (WRANs) to provide wireless broadband access while protecting the incumbent licensed signals in the TV broadcast bands. The standard is intended to utilize efficiently the sparsely populated digital television spectrum in rural areas . These WRANs are intended to utilize the channels in the ultra‐high‐frequency and very‐high‐frequency bands assigned to the TV broadcast services in the frequency range between 54 and 862 MHz.…”

This paper presents an integrated scheme for the dynamic‐frequency‐hopping (DFH) technique provided in literature for the IEEE 802.22 standard supporting wireless regional area networks (WRANs). The performance of DFH is analyzed thoroughly for various channel models and for a multiple‐input multiple‐output systems. The core of this research is based on the coexistence of digital terrestrial TV broadcasting and the WRANs in the TV white space. The proposed technique aims at protecting the incumbent users from interfering with the cognitive broadband access in the TV spectrum. In order to achieve this, spectrum sensing is performed in the intended working channel in DFH while spectrum monitoring with an energy‐ratio (ER) algorithm is applied during the WRAN data transmission in the working channel. Hence, in the DFH‐ER algorithm, the reappearance of a digital terrestrial TV signal in a band occupied by the WRANs would be detected immediately. This will provide interference free performance for the licensed signal as well as reliable data transmission for the unlicensed ones. Both analyses and simulation results of the proposed DFH‐ER technique compared with the conventional DFH scenario exemplify the enhancement of the WRAN data transmission while protecting the digital terrestrial TV users.
